| 1 | Recently duplicated sesterterpene(C25) gene clusters in Arabidopsis thaliana modulate root microbiota显示文摘Land plants co-speciate with a diversity of continually expanding plant specialized metabolites(PSMs) and root microbial communities(microbiota).Homeostatic interactions between plants and root microbiota are essential for plant survival in natural environments.A growing appreciation of microbiota for plant health is fuelling rapid advances in genetic mechanisms of controlling microbiota by host plants.PSMs have long been proposed to mediate plant and single microbe interactions.However,the effects of PSMs,especially those evolutionarily new PSMs,on root microbiota at community level remain to be elucidated.Here,we discovered sesterterpenes in Arabidopsis thaliana,produced by recently duplicated prenyltransferase-terpene synthase(PT-TPS) gene clusters,with neo-functionalization.A single-residue substitution played a critical role in the acquisition of sesterterpene synthase(sesterTPS) activity in Brassicaceae plants.Moreover,we found that the absence of two root-specific sesterterpenoids,with similar chemical structure,significantly affected root microbiota assembly in similar patterns.Our results not only demonstrate the sensitivity of plant microbiota to PSMs but also establish a complete framework of host plants to control root microbiota composition through evolutionarily dynamic PSMs. | Qingwen Chen Ting Jiang Yong-Xin Liu Haili Liu Tao Zhao Zhixi Liu Xiangchao Gan Asis Hallab Xuemei Wang Juan He Yihua Ma Fengxia Zhang Tao Jin M.

| 2 | Measuring high orbital angular momentum of vortex beams with an improved multipoint interferometer显示文摘A multipoint interferometer(MI),uniformly distributed point-like pinholes in a circle,was proposed to measure the orbital angular momentum(OAM)of vortex beams[Phys.Rev.Lett.101,100801(2008)],which can be used for measuring OAM of light from astronomical sources.This is a simple and robust method;however,it is noted that this method is only available for low topological charge because the diffracted intensity patterns for vortex beams with higher OAM will repeat periodically.Here,we propose an improved multipoint interferometer(IMI)for measuring the OAM of an optical vortex with high topological charge.The structure of our IMI is almost the same as the MI,but the size of each pinhole is larger than a point in the MI.Such a small change enables each pinhole to get more phase information from the incident beams;accordingly,the IMI can distinguish any vortex beams with different OAM.We demonstrate its viability both theoretically and experimentally. | QI ZHAO MIAO DONG YIHUA BAI YUANJIE YANG | 2020 | Photonics Research2020，8，5： | 7 |
| 3 | Improving Throughput of Communication Link in IEEE 802.15.4 Based Energy-Harvesting Wireless Sensor Network显示文摘It is critical to design a reliable packet transmission scheme to improve throughput in Energy harvesting Wireless sensor network(EH-WSN)or Battery free Wireless sensor network(BF-WSN).We present the Optimal size and rate(OSR)scheme to improve throughput of communication links in the IEEE 802.15.4 based BF-WSN that harvests radio frequency energy.Based on the defined truncated geometrical distribution,we formulate the optimization problem that maximizes the effective throughput of communication link.The solution of the optimization problem yields the optimal triple,namely the optimal packet size,data rate,and Maximum number of transmission trials(MNTT),which is used in the OSR so that throughput is considerably improved.Simulation results show the OSR scheme can improve throughput. | BAI Nana GONG Siliang SHI Haiyan CHENG Zhen ZHU Yihua | 2019 | Chinese Journal of Electronics2019，28，4： | 4 |
| 4 | Impeded degradation of perovskite solar cells via the dual interfacial modification of siloxane显示文摘It is challenging to improve the long-term stability of perovskite solar cells(PSCs) without sacrificing efficiency. The perovskite absorbers degrade from the film surface/interfaces, which follows entangled mechanisms that have not been fully revealed yet.Herein, we decouple and elaborate two distinctive pathways regarding film degradation based on FACsPbI3perovskites.Moreover, a dual interfacial modification strategy has been developed for improving the material’s intrinsic stability, thus leading to the film degrading in a more retardant pathway. The corresponding PSCs achieve a stable power output efficiency of 23.75%.More importantly, the unencapsulated PSCs devices retain over 93% of their initial PCE after the maximum power point(MPP)tracking under the continuous 1-sun illumination and show significantly improved stability after aged under the thermal treatment or stored in ambient atmosphere for over 1500 hours without obvious PCE decay. This work shows the importance of modulating the degradation pathway on stability improvement, and at the same time, proposes a strategy for designing perovskite-based optoelectronics with excellent performance and stability. | Xiao Zhang Changsu Cao Yang Bai Cheng Zhu Huachao Zai Sai Ma Yihua Chen Zhenhua Cui Congbo Shi Chenyue Wang Chenxiao Zhou Guizhou Yuan Ziyan Gao Jiawang Hong Jie Dou Hao Wang Huanping Zhou Hai Xiao Jun Li Qi Chen | 2022 | Science China Chemistry2022，65，11： | 0 |
| 5 | Stress compensation based on interfacial nanostructures for stable perovskite solar cells显示文摘The long-term stability issue of halide perovskite solar cells hinders their commercialization.The residual stress-strain affects device stability,which is derived from the mismatched thermophysical and mechanical properties between adjacent layers.In this work,we introduced the Rb_(2)CO_(3)layer at the interface of SnO_(2)/perovskite with the hierarchy morphology of snowflake-like microislands and dendritic nanostructures.With a suitable thermal expansion coefficient,the Rb_(2)CO_(3)layer benefits the interfacial stress relaxation and results in a compressive stress-strain in the perovskite layer.Moreover,reduced nonradiative recombination losses and optimized band alignment were achieved.An enhancement of open-circuit voltage from 1.087 to 1.153 V in the resultant device was witnessed,which led to power conversion efficiency(PCE)of 22.7%(active area of 0.08313 cm^(2))and 20.6%(1 cm2).Moreover,these devices retained 95%of its initial PCE under the maximum power point tracking(MPPT)after 2700 h.It suggests inorganic materials with high thermal expansion coefficients and specific nanostructures are promising candidates to optimize interfacial mechanics,which improves the operational stability of perovskite cells. | Cheng Zhu Xi Wang Hangxuan Li Chenyue Wang Ziyan Gao Pengxiang Zhang Xiuxiu Niu Nengxu Li Zipeng Xu Zhenhuang Su Yihua Chen Huachao Zai Haipeng Xie Yizhou Zhao Ning Yang Guilin Liu Xueyun Wang Huanping Zhou Jiawang Hong Xingyu Gao Yang Bai Qi Chen | 2023 | Interdisciplinary Materials2023，2，2： | 0 |

| 7 | Improved interfacial adhesion for stable flexible inverted perovskite solar cells显示文摘Flexible perovskite solar cells have attracted widespread attention due to their unique advantages in lightweight,high flexibility,and easy deformation,which are suitable for portable electronics.However,the inverted(p-i-n)structured devices suffer from poor stability largely due to the low adhesion at the brittle interface(the hole transport layer/perovskite).Herein,zeolitic imidazolate framework-67(ZIF-67)is applied to inverted structured cells to optimize the interface and prolong the device lifetime.As a result,the flexible devices based on ZIF-67 obtain the champion power conversion efficiency of 20.16%.Over 1000 h under continuous light irradiation,the device retains 96%and 80%of its original efficiency without and with bias,respectively.Notably,devices show mechanical endurance with over 78%efficiency retention after 10,000 cycles of consecutive bending cycles(R=6 mm).The introduction of ZIF-67 suppresses the cracking in device bending,which results in improved environmental stability and bending durability. | Jie Dou Qizhen Song Yue Ma Hao Wang Guizhou Yuan Xueyuan Wei Xiuxiu Niu Sai Ma Xiaoyan Yang Jing Dou Shaocheng Liu Huanping Zhou Cheng Zhu Yihua Chen Yujing Li Yang Bai Qi Chen | 2023 | Journal of Energy Chemistry2023，，1： | 0 |
